UNITED STATES PATENT FREDERICK B. BROWVNELL, OF ST. LOUIS, MISSOURI.

PASSENGER-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 380,617, dated April 3, 1888.

Application filed October 13, 1884. Serial No. 145,377. (No model.)

To aZZ whom it may concern:

Be it known that I, FREDERICK B. Buown- ELL, of the city of St. Louis. in the State of Missouri, have invented a certain new and useful Improvement in Passenger-Vehicles, of which the following is a full, clear, and exact description, reference being bad to the accompanying drawings, forming part of this specificaiion. A This invention is in some respects an improvement on the invention contained in the Patent No. 247,608, granted to me September 2-7, 1881.

The invention will be described as applied to a street-railway car. It can be applied in the same manner to other passenger-vehicles.

Figure 1 is a detail transverse section of one side of a carbody, showing the sash down; and Fig, 2 is a similar section of the other side of the car-body, showing the sash raised. Fig. 3 is an inside view of a sash with adjacent parts. Fig. 4 is a side view of the springbalance pulley with partof its case removed.

A part of the car-tioor is shown at A.

Bis the end of the body.

C are the side post-s.

D are the rafters forming extensions of the posts.

13) are the guide-grooves of the sash. These grooves are inclined inward in the posts, have continuous (unbroken) sides, and extend up the sides of the posts and up the sides of the rafters. The grooves are usually made by nailing guide-strips upon the sides of the posts and rafters.

The sash F has at each corner a guidestud, G, projecting horizontally in the plane of the sash and entering the groove, thus forming the bearings of the sash as it is raised and lowered.

It will be seen that the inclination of the grooves causes the sash to lean inward, so that when the latter is raised the upper guide-studs will readily follow the curved grooves of the rafters.

The construction thus far may be similar, with the exception of the continuous (unbroken) sides, to that described in my patent aforesaid; but the means for sustaining the sash in any desired position is altogether different, and will be now described.

Within a pocket, 0, inside the top side panel, C, of the body is a pulley, H, turning on a fixed arbor, I, secured to the side of a post and having within it acoil-spring, J. One end of the spring J is secured to the arbor I and the other end to the rim of the pulley, so that when the pulley is turned in one direction it will wind up the spring.

K is a metal ribbon, which is coiled upon the pulley H, one end being attached to the pulley and the other end of the ribbon being attached to one of the corners of the sash on the front of the latter, so that it will have the tendency to tip the sash inward to follow the inclined grooves. The arrangement is such that as the sash is lowered the spring J is wound up, so that its tension supports the sash at any point, the weight of the sash about equaling the tension of the springs of two balancing-pulleys at the opposite sides of the sash. The pulleys are inclosed in a case, L. The outer end of the arbor is supported on a bracket, M.

In summer time the sashes are in many cases removed and slatted blinds put in their place. These blinds would be supported in precisely the same manner as the sashes, and would form a full equivalent of the same. In place of the spring-pulley, I may use a counterbalance weight as an equivalent of the spring-pulley. The connection between the counter-balance and the sash or blind need not be made to the bottom of the sash or blind, but may be made to any other part of the face.

I claim- The combination of the posts 0 and rafters D, having the inwardly inclined and curved grooves E extending through them, a sash, F, having corner'studs Gworking in the grooves, and a counter-balance consisting of a bracket, M, pulley H, having arbor I secured to theside of the post and supported in the bracket, spring J, connected to the arbor and pulley, ribbon K,secured to the sash, and case L, substantially as shown and described.

FREDERICK B. BROWNELL.
